I have a brother model MFC 6490cw. The BLACK PRINTHEAD has

Resolved Question:

I have a brother model MFC 6490cw.
The BLACK PRINTHEAD has become clogged.
I tried a new cartridge, no change.
I went thru over 1/2 of the new ink cartridge trying to clean. I also used up most of the ink in the three colors thinking that might help. The result was now change.

What can I do???

Most likely this is a print head issue. The print head is what the cartridges sit in inside of the printer. To attempt to resolve it, do the following:

(1) Open the printer
(2) Remove the ink cartridges from the print head.
(3) Use cotton swabs dipped in hot water to thoroughly clean the print head and each ink cartridge.
(4) Repeat this until there is no ink residue coming off on the cotton swab.
(5) Once finished, allow to dry and replace the cartridges
(6) Try to print something now

If that does not work then you have one of two possibilities:
(1) One of the ink cartridges is defective and causing the error
(2) If it's definitely not that, then the print head will need to be replaced.

Give me instructions on how to get to the printhead.

tell me what the cost of a new printhead would be and where I can get one.

Expert:  Robert Preston replied 6 years ago.
Take out the cartridges and clean the area under them thoroughly first

The printhead is unfortunately close to $200 for this model... so replacing it may not be that practical

You did not give me DETAILED instructions as to:

Where the printhead is located on my model?

How do I extract it from the printer?

How do I reinsert the printhead?
